Insights
Systemic lupus erythematosus (SLE) patients face high cardiovascular disease risks. Advanced imaging now helps detect early atherosclerosis, offering better insights into vascular disease mechanisms in SLE.
Area of Science:
- Rheumatology
- Cardiology
- Vascular Medicine
Background:
- Systemic lupus erythematosus (SLE) significantly increases the risk of premature cardiovascular disease (CVD).
- CVD is a leading cause of mortality in SLE patients.
- Previous studies likely underestimated CVD prevalence by relying on overt clinical events.
Purpose of the Study:
- To review vascular imaging techniques for assessing CVD in SLE.
- To highlight the shift towards detecting subclinical atherosclerosis.
- To understand the true prevalence and mechanisms of vascular disease in SLE.
Main Methods:
- Discussion of various vascular imaging techniques.
- Focus on detecting subclinical atherosclerosis.
- Emphasis on structural and functional vascular changes over flow-limiting stenosis.
Main Results:
- Sensitive imaging techniques allow for better detection of subclinical atherosclerosis.
- Atherosclerosis is a key determinant of coronary heart disease.
- Current trends favor assessing early vascular changes.
Conclusions:
- Vascular imaging is crucial for understanding CVD in SLE.
- Detecting subclinical atherosclerosis provides a more accurate assessment of risk.
- Future research should focus on early structural and functional vascular assessments.
Abstract:
Patients with systemic lupus erythematosus (SLE) are at significant risk for premature cardiovascular disease, now a leading cause of death in this population. Most previous studies have used an overt clinical event to identify cardiovascular disease, likely underestimating the actual prevalence in these patients. Although the rates of myocardial infarction in SLE are high, the actual number of coronary events is low, precluding large clinical trials using a coronary event as the sole outcome. The ability to measure atherosclerosis, a known determinant of coronary heart disease, provides investigators with a desirable surrogate for the clinical cardiac event. With the advent of sensitive imaging techniques to identify subclinical atherosclerosis, we are now better equipped to determine the true prevalence and mechanisms of vascular disease in SLE. In this review, we will discuss several vascular imaging techniques and the current trend away from measuring flow-limiting vessel stenosis toward measuring earlier structural and functional aspects of the vascular system.
